Sky-Watcher | Evostar 80EDX (OTA)

The optics of the telescope:

The proven Sky-Watcher Evostar-80ED doublet apochromatic refractor has undergone several remarkable improvements. We are pleased to present the new Evostar-80EDX model, which has benefited from a series of very useful mechanical enhancements. It comes in a beautiful white/green finish. The Evostar-80EDX is an excellent instrument for both visual observation and photographic use with all necessary accessories.

The new EVOSTAR-80EDX model now includes a 2.8-inch indexed focus tube with an integrated 360° rotating adapter, a retractable dew shield, and a convenient carrying handle.

It features the same proven f/7.5 optics as the previous model, which includes a high-end Japanese Ohara FPL-53 ED lens that eliminates visible chromatic aberration. The 0.85x focal reducer/field flattener (20236) is available as an option for photography.

The optics provide stars with great sharpness against a pitch-black sky background and very high contrast. Each glass-air surface is coated with an exotic metallic treatment that allows for an impressive light transmission of 99.5%. Sky-Watcher's proprietary “Metallic High-Transmission Coatings” (MHTC) are among the most precise anti-reflective coatings in their class.

Apochromatic refractors, thanks to their unobstructed diffraction patterns resembling that of text, produce the sharpest optical image and the best possible quality for this aperture among all available optical systems.

For a long time, Evostar-ED doublets have been the best choice for photographic refractors for many astrophotographers, thanks to their combination of excellent image performance and competitive pricing. Due to the use of little glass in their construction, they are usually lighter and therefore more comfortable to transport than comparable triplets or other multi-lens ED refractors with this aperture.
